Introduction
The ELVR Series Mini Analog and Digital Output Sensor is
based on All Sensors’ CoBeam
2 TM
Technology. This reduces
package stress susceptibility, resulting in improved overall
long term stability. The superior dual-die technology also
vastly improves position sensitivity compared to single die
devices. This technology breakthrough advances the state of
the art for piezoresistive pressure sensors beyond what has
been achieved for low pressure sensing using silicon based
strain technology.
The ELVR sensors can communicate directly with microcon-
trollers, eliminating the need for additional A/D converters.
ELVR series pressure sensors are available at 3V and 5V
supply voltage. The ELVR series provides a rapid update rate
at multiple resolutions. A wide range of miniature SIP and
DIP package options allows for flexible and space-saving
PCB-mounting. These calibrated and compensated sensors
provide accurate, stable output over a wide temperature
range. This series is intended for use with non-corrosive,
non-ionic working fluids such as air and dry gases. A pro-
tective parylene coating is optionally available for moisture/
harsh media protection for pressure ranges 10 inH2O and
above.
The ELVR Series is a direct replacement to First Sensors’
HCLA product line. Refer to the product web page for a

Specification Notes
Note 1:
For any pressure applied the output response time to reach 90% of pressure applied.
Note 2:
Shift is relative to 25°C between standard or industrial compensated temperature
range endpoints.
Note 3:
Shift is within the first hour of excitation applied to the device.
Note 4:
Measured at one-half full scale rated pressure using best straight line curve fit.
Note 5:
The span is the algebraic difference between full scale output voltage and the offset voltage.
Note 6:
Parameter is characterized and not 100% tested.
